Biochemical tests and use of media allow physicians to identify
the type of bacteria causing a disease (such
as whether its gram+ or gram-) and use appropriate
antibiotic effective against the bacteria. Another clinical significance is to
determine the resistance of bacteria to antibiotics (this is conducted using susceptibility tests).
C is the answer
:) for your question (im writing extra cause answer is too small)
Answer:
Polytene chromosomes may be defined as the giant chromosomes that contain alternate dark and light bands when view under the microscope. These chromosomes are found in the salivary gland of Drosophila.
These glands are functionally highly active and contain thousand of DNA strands. These chromosomes are aligned parallel with each other as the replication is normal but the cells are unable to separate and fails to undergo the process of cytokinesis.
It would be B. Less force is needed to move up the ramp
Lll. a limited supply of necessary resources. If there isn't enough resources the species will have to learn to adapt to be able to gather the new food supply they need. Such as birds and there beaks, if the insects population went down and that was the main food supply for that type of bird they would have to be able to adapt in order to survive, so evolution occurs. Over time that bird would change to adapt to its new feeding source.
Hope this helps!
